Some missions freeze with mods.

I am having this problem. I am using mods, obviously, and when I play story mission with them active in some the game wont let me continue the mission. I loads without and end, or I cant swich to Franklin in Paleto bay heist, or when infiltrating Humane labs when I get Michael to the bars and he should cut them, nothing happens.
Is there any fix for this?

I have been testing with my game save VS the 100% save game from here. My personal save will crash at a specific point every time. Using the 100% Savegame I can replay that mission and though it will crash at the same point It will suddenly work the next time I replay that mission. I can't explain how it works.

The only work around I found is to fail, fail, fail until the game gives you the option to skip the mission. Either the whole mission or just that checkpoint.
